Genes affected

ADAMTS20 (HGNC:17178): (ADAM metallopeptidase with thrombospondin type 1 motif 20) The protein encoded by this gene is a member of the ADAMTS family of zinc-dependent proteases. The encoded protein has a signal peptide that is cleaved to release the mature peptide, which is secreted and found in the extracellular matrix. This protein may be involved in tissue remodeling.

The c.4732C>G (p.L1578V) alteration is located in exon 31 (coding exon 31) of the ADAMTS20 gene. This alteration results from a C to G substitution at nucleotide position 4732, causing the leucine (L) at amino acid position 1578 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
